Android Studio, JSON Object too long

I followed a tutorial for an JSON Parser and tried to use it for another request with the same api. But now it always fails when trying to parse it to a JSON Object.

This is my JSON parser:

public class GetProvider extends AsyncTask<String, String, String> {
    protected String doInBackground(String... params) {
        String current = "";
        String providerURL = "https://api.themoviedb.org/3/movie/" + model.getId() + "/watch/providers?api_key=" + api_key;

        try {
            URL url;
            HttpURLConnection urlConnection = null;

            try {
                url = new URL(providerURL);
                urlConnection = (HttpURLConnection) url.openConnection();

                InputStream is = urlConnection.getInputStream();
                InputStreamReader isr = new InputStreamReader(is);

                int data = isr.read();

                while(data != -1) {
                    current += (char) data;
                    data = isr.read();
                }
                is.close();
                return current;
            } catch (IOException e) {
                e.printStackTrace();
            } finally {
                if(urlConnection != null) {
                    urlConnection.disconnect();
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return current;
    }

    @Override
    protected void onPostExecute(String s) {
        try {
            JSONObject jsonObject = new JSONObject(s);
            JSONArray jsonArray = jsonObject.getJSONArray("results");

            for(int i = 0; i < jsonArray.length(); i++) {
                JSONObject jsonObject1 = jsonArray.getJSONObject(i);
                model.setProvider_id(jsonObject1.getString("provider_id"));
                model.setProvider_name(jsonObject1.getString("provider_name"));
                System.out.println("Stop");
            }
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}

When running it fails with:

W/System: A resource failed to call end.

It doesn't even show the whole value. how can I get the whole value/fix that?
